A very famous breeder once told me bear dogs were the easiest working dogs to breed, I asked what do you mean, his response was that those with more guts than brains the bears kill, those that quit or don't finish races I kill that only leaves me the good ones to breed.
I prefer to breed and raise curs that can stop and hold a boar hog...that has been a big challenge...mother nature tends to help me now and then as you mentioned about that bear hunter...
hunting to hard in the hot summer can cull a dog...to gritty of a dog can cull the dog...fighting a hog and trying to kill it can over heat the dog and that dog can die because of it...I now cheat mother nature a little with running vest and the alpha 100...I will breed dogs that stop hog as best as possible...at times these dogs can be bay busters but gritty dogs are the type I prefer...
